The big selling point about the MR-100 is its aesthetic appearance. With its small, but most certainly well formed design, it's quite easily the most visually appealing MP3 on the market. The single piece of glass that covers the front of the unit looks and feels almost perfect. There are no poorly constructed edges, obviously Olympus haven't scrimped on the cost of putting the whole unit together. The back of the unit is metal coated with a touch of white paint, which compliments the pure black front quite nicely indeed.
